My Mk1a V6 Wiring Diagram

[Paul Woods]

im afraid the wiring schematics are permenantly etched into my head owen! either that or im extremely sad...

theres a problem with that diagram on the check engine light,pin 4 on the 4th ecu plug is for CEL (usually green) and that should go to pin 1 on the N1..... in the diagram you have pin 1 on the N1 going to pin 9 on the 4th ecu plug which is wrong.

Also it might be worth adding pin 1 on the 4th ecu plug joined onto pins 12 and 13 as this is 95% the case with v6 ecu's,yours is the rare exception that we have only found once so far with no pin 1.

Other than that its a great diagram :thumbsup:

Lol, blimey that was quick :thumbsup:

That will explain the lack of my "check engine" dash light and was going to be the subject of my next post :)

I have changed it over and everything seems to work great.
Diagram updated too.

Added you as number 11 to the swap register. Bloody well done mate!

Owen.

Cheers owen :)

Nice 1 :)

[Paul Woods]

good stuff,pin 1 though? can you add that with a * attached and then something like

*most v6 ecus have pin1 B/O present however some dont

or something like that?

Sorry, I got all excited and dashed outside to swap wires and forgot that bit :)
Done

Nice one mate, on both the startup and the write-up, saved me doing it :D

Nobody would trust your wiring diagram anyway :hidesbehi

[OlberJ]

Nope and neither would i so it'd mean they all get double checked.

It can never be a bad thing :)

Ok, what about the reversing lights?
The wires on the v6 loom seem to head straight to the ECU.
How do we get the signal to the lights?
i.e. where on the car do we connect them?

Cheers
